SPRAYING DEVICE.

Application filed October 11, 1926, Serial No. 140,887, and in Great Britain October 16 1925.

This invention relates to spraying devices for personal ablution of the kind which is provided with means for connecting it to two bath-taps and for supporting it from a part of the bath structure in such position that the spray therefrom is directed within and along the bath.

According to this invention a device of this kind is provided with a mixing-chamber having baffles arranged within it to cause water flowing therethrough from the hot and cold water supplies to become thoroughly mixed before being discharged.

The mixing chamber may be an elongated (for example cylindrical) chamber having means at each end thereof for attachment to a bath-tap for support thereby (for -ex ample in a horizontal position) and provided with spraying apertures in the wall thereof on the side facing the remote end of the bath.

Preferably the mixing-chamber is annular in form, being provided by a central tube and a jacket surrounding the tube (which jacket is provided with spraying-apertures in its wall on one side thereof), and the aforesaid baffles extend lengthwise thereof in a staggered manner for the purpose of causing water entering the chamber from an aperture in the wall of the central tube to follow a tortuous course from end to end of and around the chamber on its way to the spraying apertures. Thus cold water supplied to one end of the central tube and hot water supplied to the other end become thoroughly mixed before leaving the apertures.

The ends of the central tube may project beyond the jacket to receive connectingpieces (for example, corrugated rubber tubes) for attachment to the bath-taps.

A practical embodiment of the invention is illustrated by way of example in the accompanying drawings, in which:

Figure 1 is a transverse section through a bath and shows a spraying device according to the invention connected to the taps:

Figure 2 is an elevation of the spraying device with. the connecting means removed;

Figure 8 is-a section on the line 33 of Figure 2.

Figure 4 is a perspective view of the spraying device with the outer jacket shown in dot-and-pick lines for clearness, and

Figure 5 is a developed view of the inner tube and baffles thereon with the outer acket and end annular plates removed.

The spraying. device illustrated in the lialf in bore, thus providing an annular chamber 12 about one-quarter ofan inch in width, which chamber is closed by an annular end-plate 13 at each end. The central tube projects beyond the jacket 11 equally at its ends, these projecting ends 1% serving for the attachment of connecting-pieces 15 of corrugated rubber tubing, the free ends of which can be pushed over the nozzles of the two hath-taps 16,,so that the device is supported horizontally beneath and between the taps as shown in' Figure 1.

An opening 17 is provided in the wall of the central tube 10 at one end, and spraying apertures 18 are'provided in the jacket .11 along one'side' thereof. There may be four rows of apertures equally spaced, the. extreme rows being separated by an angle of about 60, and the apertures of adjacent rows are staggered.

The opening 17 is adjacent one extreme row of apertures, but is separated therefrom by a partition 19 extending from end to end of the annular chamber 12. Thus water ontering said chamber through the opening 17 must pass round the chamber to reach the spraying apertures 18.

Adjacent the other extreme row of apertures is a second partition 20 having a gap 21 (Figure 5% at each end for the passage.

of water, anc in order to ensure that hot Water'and cold water supplied to opposite ends of the central tube 10 shall be completely mixed before reaching the spraying apertures 18. Fourbafiles 22, 23, 24 and 25 are providedwhich are so formed as to compel the water to follow a tortuous course.

The first baffle 22 extends from one end of the annular chamber 12say therighthand end as shown in Figure 5-along the side of the opening 17 opposite to that on which'the partition 19 is located and longitudinally of said chamber to a point near the other end thereof. The second .baffle 28 extends from theleft-hand end along the chamber 12 to a point near the opposite end, the third 24 extends from the right-hand end to a point just short of the centre of length of the chamber 12, is there bent at right-angles towards the second bailie 23 and is again bent at right-angles and con- I .tinued towards the left to a point near the left-hand end, and the fourth 25 extends from the left-hand end in line with the root of the third baffle 24; to a point just short of the centre, where it is bent at rightangles towards the cranked portion of the third battle but does not reach the latter. The root portions of the third and fourth baffles 24, 25, respectively are parallel to and adjacent the partition above described, and it will be evident that water entering the chamber 12 through the opening 17 in the central tube 10 will flow first towards the left, then towards the right, again towards the left, around the cranked end of the third baflie 24 and between the adjacent ends of the root portions of the third and fourth baiiies 24, 25 respectively,

into the space 26 between them and the partition 20 as shown by the arrows in Figure 5. In the space 26 the water divides and flows towards the ends thereof and through the gaps 21 at the ends of the partition 20 into the space 27 between the two partitions 19 and 20 which constitutes the spraying chamber. Thus the hot and cold streams are thoroughly mingled before leaving the spraying apertures 18.

Although the device has been described as supported from the bath-taps, it is evi-' dent that it may be otherwise detachably supported from a part of the bath structure,

like, comprising a mixing-chamber, means at each end thereof for attachment to the hot and cold. water bath-taps for support thereby, baiiles therein for causing a tortuous water circulation, and apertures in the wall of the mixing chamber for spraying the thoroughly mixed water.

2. A spray. device for bath tubs and the I like, comprising an annular mixing chamber having a central tube, a jacket surrounding said tube, said jacket having spraying apertures in its wall on one side thereof, the chamber between said central tube'and said jacket being provided with staggered baflies extending lengthwise thereof, and an inlet aperture in the wall of the central tube leading to said chamber, whereby the water from said central tube follows a tortuous path through said chamber to the spraying apertures.
